To all 'whom t may concern:

Be it known :that I, EMU.. OHRIs'rnN sm', citizen of Vthe United ffStates, resident of Portland, county of Multnomah, State of Gregori, have invented certain new -and useful Improvements'in Tapping Devices, of which-*the follow-ing isa specification.

Myinvent-ion Lrelates to a dev-ice for tapping barrels, kegs, yorother liquid receptacles for the removalof the contents, and particq ularly for tapping beer kegs, the device being appliedv at the faucethole that: isk sealed by zany Vof the ordinary faucet plugs or bungs. A

The object'of'my invention is tov provide a tap bushing for itting within' the hole in the barrel or keg and'having means for engaging ,the sea-ling cork'to hold it securely and at ythesame time present a smooth surface on which sediment and foreign matter cannot lodge, and a surface which will not tear or mutilate thecork.

A further object is to provide a. bushing which will providea positive seal for the cork, will permit the use of va common wooden faucet when a tap is not available, and will not require the use of a special plug when the barrel is pitched, as it often is in some of the breweries when returned empty.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is a vertical sectional view through a tapping device embodying my invention, showing its application t-o a barrel,

Fig. 2 is a detail sectional view, showing a cork in position to be forced into the bush- 111g,

Fig. 3 is a similar view, showing the cork in its sealing position within the bushing,

Fig. 4 is a detail view of the end of the tap plunger,

' In the drawing, 2 represents the head of a barrel or keg and 3 is a bushing inserted into the bung or faucet hole therein and having a laterally extending ange 4 at its outer end terminating in a rib or lip 5 that is flush substantially with the surface of the head when the bushing is inserted therein. rThis iiange, with the rib or lip, has the function of centering the tap corker or corking Specication of Letterslatent..

machine,4 and the rib prevents the gasket seated on theflangefroni'spreading when the tap is screwed into the bushing, and also forms an edgefforv tearing a hole 'in the Y plug is forced into the-bushing and-held by the ribof the threadl therein, theinner end of the cork being forced through the circular opening and gripped by the walls thereof and completely sealing the opening through the bushing.

The course, wide thread lof the'bushing, while-gripping the Acork yorplug securely, willA not cut or tear it, as ordinary threads would',"and the inne-r surface of the bushing, being comparatively smooth, no particles of foreign material can lodge thereon and contact with the contents of the barrel. Furthermore, this form of thread will permit the use of a common wooden faucet, where the tap designed for the purpose may not be convenient or available. A tap barrel 9 is provided, having a flange 10 between which and the iiange 4: a packing ring 11 is inserted, and at the end of the barrel is a threaded portion 12 that is formed to tit the coarse thread on the inner surface 'of the bushing and force the cork or plug inwardly through the bushing when it is desired to draw off the contents of the barrel. For convenience, the inner end of the tap 12 may be provided with teeth 13, but this is not essential, as the engagement of the thread on the tap with the thread of the bushing will insure the dislodgement of the cork or plug when the tapping device is rotated. The tap barrel 9 has an air supply attachment 14 of ordinary construction, and at its outer end is provided with a nut 15 engaging the eXteriorly threaded end of the barrel in which a packing gland 16 is arranged to encircle the tapping tube 17 that is inserted through the nut 15 and the tap barrel and through the bushing into the contents of the barrel in the usual way. I make no claim to this feature of the device, as it is old in articles of this kind, the invention consisting in the tap bushing having the coarse threads and the circular opendi i having' plain walls, that a Sure seal foi the coih is formed as it will iit snugly against the plain surface, Whereas, when the bushing is threaded from end to end, the sharp edge of Vthe thiead Will not form a tight joint with the eoil, but permit. a leak around the cork, following lengthwise of the thread. l iegaid this featiiie, therefoe, as an ini:V portant part of niy invention.

in vaiiious Ways the details oi' Construction herein shown and described may be modified andV still be Wit iin the Scope of my invention. Y Y

l claim as iny invention:

l. A tapping device having a bushing adapted to be inserted into the bung or ianoet-hole of a barrel head and having a Coarse thread on its inner surface for engagement with the Wallsof a Cori; inserted into said bushin, said thread being in the ioin subetantially oiga spiral i'ib projecting into the opening through the bushing and the Wall of the bushing being concave between the Vconyoliitions of said rib and Curved to aling and engage Said cork, the suiface of naeenee said Vend portion having a spirally formed recess to receive said rib and a Convex curved surface to eopeate with the oppositely curved surface of Said bushing when the tap is insei'ted therein, and the inner' end of said bushing having a smooth intelnal surface against which the end of the eoil is seated to oini a seal theiefoi.

Q. n. tapping device having a bushing adapted to be ineeited into the bung or fain cet hole of a bai'rel head and having a coarse thiead on its innen sufaee for engagement with the Walls of a coil inseited into Said bushing, said thread being in the form substantially oi a spiral iib projecting into the opening througi the bushing, and the Wall oi'.l the bushing being concave between the coniolntions of said rib and euived to allen7 the coil; to slide ieely thereon, a taphaving an end portion to iit into said bushing and engage said coiik, the surface of VSaid end portion having a spirally formed iecees to receive said iib and a convex curved euifaee to eopeiate with the oppositely eui'ed Surface of Said'bushing when said tap is inserted therein.

ln Wit-ness whereof, have hereunto set my hand this 25th day o1" May 1914.
